We all heard the story of "Monkey Going Up the Mountain" when we were children. Because the monkey didn't know what he wanted, he could only go down the mountain empty-handed. In urban life, we pursue material and love, career and marriage, freedom and family, excitement and stability. Because we want too much but cannot have it at the same time, we must make a choice. So, we all become the monkeys on the mountain who keep choosing. There are smart monkeys who choose what they want, and there are greedy monkeys who have nothing because they cannot choose. Hopefully, you and I are both smart monkeys.
